And infamously the ill fated Fisker Karma

Wonderful writeup! Really embraces the old internet character from the days before people started putting ads in the personal websites.

If you are riding the Geerling train you would probably be interested in the upcoming mono router: https://www.jeffgeerling.com/blog/2026/testing-mono-gateway-...

Personally I use an x86 PC (supermicro E300 with X11SDV motherboard with integrated Intel X540 10Gbe NICs) running opnsense.

That depends on the application, the standard for short range (<100m -- fine for most anything that doesn't leave your building) is already to use 800nm.

For what it is worth, no graduate student would say they are doing 'Ph.D level' research. It is called 'graduate level research' or just, you know, 'research'

Sounds like a fun project, I wish you the best. I ran a similar program (independent study that encouraged freshman/sophomore undergraduates to explore using microprocessors, at the time the EE curriculum was completely focused on analog circuit theory and ended at boolean logic) and it went well enough that it eventually became part of the official undergraduate curriculum.

Would you care to explain how the NICT guys achieved 402Tb/s through a single (50km long!) fiber back in 2024 then? It seems like another factor of two would easily be in reach if they could extend their setup into the visible.

There have been leaps and bounds of progress in the last few years. Youtube hardware acceleration works perfectly in chrome/firefox now (assuming you have working video drivers).

As far as I know netflix still limits you to 720p under most browsers (although their support page shows that opera of all things supports 1080p)

If you hold out for a few more paragraphs until he gets past the installer there is closure:

The issue is that he was using an obscure gaming mouse, and the solution was to use a different mouse.

The second to last bullet point on the post is about the Samsung client, which (as you are aware) has been written but is currently held up in review Samsung. The first round of review took about 3 months(?!), and they are working through reproducing the vaguely stated issues found in the review.

It is thankless work, but they are actually quite close!

no the op, but I find great joy in looking though who sends me spam (based on the unique email used to sign up for each service)

I think it scratches a similar itch to putting up a game camera to see what sort of vermin are running around in your back yard.

Not OP but I have had a set of the bose noise canceling earbuds that I have worn 5 days a a week for over 5 years now and absolutely love them. Noise canceling is excellent, comparable to the over-the-ear-style.

My main complaint is the onboarding process really pushes you to install their app. It is entirely unnecessary (can configure them by various tap codes) but still annoying they don't tell you that until you install the app...

I have been self hosting a matrix setup for a few years now, using the spantaleev ansible playbook. It does require updates roughly once a year to keep up with changes of the 3rd party chat APIs. Generally that involves logging into the server and running 'just update' followed by 'just install-all', but occasionally there are changes that need updates to the playbook as described in the release notes. In the worst case, if one of your bridges does go down you can always fall back to the vendor client for that protocol until you get the bridge updated.

Overall it has been absolutely rock solid, and the new element x app has been night and day compared to the old one.

Feels a lot like the days of using Pidgin chat, but since the bridges run on the server you only need to authenticate once instead of going through the process for every device.

It is incredible to see a concept going from 'optical table of sensitive equipment fraught with numerous safety concerns' to 'here is a 1 kB svg animation, stare at it for 1 minute' in 3 months.

Enjoy your forbidden color, you earned it!

After further review, the e-mail was posted on a 'who's hiring' page, so to be honest its a miracle that this isn't receiving more spam!

I got the same e-mail sent to an address unique to HN. It is a custom domain with a catch-all enabled, the e-mail only came to the HN specific address.

edit: While the above statement is true, the e-mail was posted publicly on a 'whos hiring' thread so there is no mystery as to why it is receiving spam.

deadbeef-f00d-f00d-deadbeef isn't a valid UUID v4

Aside from missing a grouping in the middle, you need the version and variant bits, ie:

XXXXXXXX-XXXX-4XXX-VXXX-XXXXXXXXXXXX

where V is 8, 9, A, or B

searching for deadbeef-f00d-400d-a00d-deadbeef does return the expected matches

Here is the product page

https://www.sifive.com/boards/hifive-premier-p550

It is based on the ESWIN EIC7700X SoC with its quad core 1.8GHz RISC-V core

https://sifive.cdn.prismic.io/sifive/ZxLjE4F3NbkBXuzW_EIC770...

You also get Imagination AXM-8-256 'GPU' on chip. You get h264/h265 encode/decode and '3d support' in a yet-to-be-released driver.

Looks like a fairly promising product -- quite a step up from the unmatched

FWIW, the current version of element (X) is published as a reproducible build on f-droid. https://f-droid.org/en/packages/io.element.android.x/

I have not been following the end-to-end encryption discussion in a while so please excuse my ignorance in asking...

How does the 'rubber hose' threat apply to Matrix? So long as you are in control of your home server (or at least use a home server you trust) I am not sure who your advisary would pressure.

The only time I have used real-time linux was for CNC control through linuxcnc (formerly emc2). https://linuxcnc.org/

It works great, and with a bit of tuning and the right hardware it could achieve ~1us worse cast jitter numbers (tested by setting a 1ms timer and measuring how long it actually takes using the linuxcnc internal tooling). Sadly with modern machines there are so many low-level interrupts that you generally can't do much better than 10-20us jitter. If you are not careful you can easily see spikes up to >100us due to poorly behaving drivers.

To be honest the never ending headache of getting things to work with SELinux under RHEL was a big driver for why I moved to debian.

Certainly SELinux has its place but I never found the value it offers to be worth the complexity it adds.

Important to note that the 'score' button doesn't work on the archive.org version

Then again any half decent hacker would know their score before clicking the button anyway ;-)

Genuinely curious - which model is this? I bought a LG C2 OLED last year (still current model) and never experienced this. It mentioned alexa support on the box, but I have never seen any popups related to it.

FWIW - on most LG TVs, you can 'revoke' your acceptance of the EULA, which essentially returns the TV to non-smart status. Most of the tiles will disappear from the home screen, as will the ads. Depending on the model you might need to futz with the settings to make sure that the TV defaults to the hdmi input instead of the homescreen when you turn it on.

The working mechanism of femtosecond (and picosecond for that matter) micromachining is the same as the coulomb explosion being discussed here. In the industry it is usually referred to 'athermal' or 'cold' to differentiate from the older system which rely on thermally heating the material to ionize it.

In fact it is mentioned explicitly in the wikipedia article:

>Coulomb explosions for industrial machining are made with ultra-short (picosecond or femtoseconds) laser pulses...Coulomb explosion etching can be used in any material to bore holes, remove surface layers, and texture and microstructure surfaces

You should upgrade your search engine.

Here is a nice survey covering some of the commercial uses: https://www.photonics.com/Articles/Ultrafast_Lasers_Are_Quic... The market for commercial femtosecond lasers systems is nearly $1B/year!

You can search for 'femtosecond micromachining' for an idea of the applications where this is being used. Most of the applications are still in high margin markets (aerospace, medical, semiconductor), but there are starting to be consumer applications in particular in the display industry. For example, cutting gorilla glass cleanly is most often done with femtosecond lasers these days.

Popularity is increasing rapidly as the cost for femtosecond lasers has been coming down. Wile you are not going to find a press release from Apple saying that they are installing a particular manufacturing technology on their iphone line, the sales numbers speak for themselves: there is a sizable fraction of 1B/year in sales of femtosecond systems which are being used to build _something_

There is one update the the article that seems noteworthy:

Seems to be this https://wonderfulengineering.com/samsung-unveils-a-qwerty-ke...

It does mention it, but later explains why they prefer plastic wrap.

Personally I use lemon juice -- not only does it chemically prevent the browning (yay chemistry) but it also makes it taste better.

It sounds like you would enjoy a career in electrical engineering. Most undergraduate EE curriculum will offer a class (usually both an undergraduate level and a graduate level version that covers more advanced typologies) specifically dedicated to answering the questions you are asking.

Lucky for you the course notes are available for many of them. For example 6.334 from MIT https://ocw.mit.edu/courses/6-334-power-electronics-spring-2...
